With an ABEC-3 precision rating and double shielded for protection, it offers exceptional durability and efficiency. Made from 400-series hardened martensitic stainless steel, it withstands corrosion and high temperatures, making it ideal for demanding environments. ## Description This double shielded Dynaroll precision miniature ball bearing is made of 400-series hardened martensitic stainless steel and has an Annular Bearing Engineers’ Committee (ABEC)-5 precision rating. The single-row, deep-groove precision miniature ball bearing is suitable for limited-space applications requiring high accuracy, high speeds, and both axial and radial loads. The bearing has deep inner and outer races that conform to the balls that run in them, allowing higher speeds and creating lower friction than bearings with comparable-sized roller bearings. It has a metal shield on either side that is fastened to the outside ring and extends over the rolling elements. The shields assist in keeping out contaminants such as dirt and grime and also help to hold in lubricant applied during manufacturing. The inner and outer rings and balls are made of a 400-series martensitic stainless steel hardened to a minimum of C58 on the Rockwell hardness scale, providing better resistance to corrosion and high temperatures than American Iron and Steel Institute (AISI) 52100 chrome steel, and higher hardness and wear resistance than plain stainless steel. This bearing has a stainless-steel cage to prevent the balls from coming into contact with each other during use, reducing friction, vibration, and noise. It can be used to a maximum operating temperature of 121 degrees C/250 degrees F. The ball bearing has a CN (normal) radial internal clearance designation, making it suitable for applications where the load and speeds do not result in thermal expansion. This clearance provides latitude for self-realignment and compensates for static and dynamic alignment errors. This bearing has an ABEC-3 rating for a higher standard of precision than ABEC-1 bearings. ABEC-rated ball bearings are manufactured to tight dimensional tolerances, making them useful in applications that require high accuracy, high rotational speeds, and increased operating efficiency. This ball bearing is for use in commercial and industrial applications including medical devices, radio controls, gearboxes, instrumentation, fishing reels, and small motors. Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All rolling bearings are open, shielded, or sealed. Sealed bearings are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use. The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others. Dynaroll Corporation manufactures miniature bearings and ball bearings that meet International Organization for Standardization (ISO), Occupational Health and Safety Assessment Series (OHSAS), Production Part Approval Process (PPAP), and U.S. Food and Drug Administration (FDA) Critical standards for quality assurance. Founded in 1988, Dynaroll is based in Sylmar, California. ## Features - Single row, deep-groove precision miniature ball bearing for limited-space applications requiring high accuracy, high speeds, and both axial and radial loads - Metal shields on both sides of the bearing keep the lubricant in and contaminants out - 400-series hardened martensitic stainless steel for better resistance to corrosion and high temperatures than AISI 52100 chrome steel - Stainless steel cage evenly spaces balls for reduced friction, vibration, and noise - CN (normal) radial clearance for applications where thermal expansion is not a factor ## Images ![Dynaroll Precision Miniature Ball Bearing, ABEC-3, Double Shielded, Stainless Steel, Metric - Image 1](https://m.media-amazon.com/images/I/71dHzLV13WL.jpg) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/30638658-dynaroll-precision-miniature-ball-bearing-abec-3-double-shielded-stainless](https://www.desertcart.com.ar/products/30638658-dynaroll-precision-miniature-ball-bearing-abec-3-double-shielded-stainless) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-05-20*
